Considering the lack of Starbreakers as of late, I'm going to add the roleplay reasoning linking to this event. I'll add a load of fake Starbreakers to the list. Feel free to invent some more, I'll fit them into the family tree somewhere.
Berren Starbreaker (Farrens twin Brother. A very stereotypical Cave Dwarf, highly racist yet taking great pride in his clan. Dissatisfied with his Brothers actions he led a score of Dwarves from the Starbreakers to join the garrison in hope that they may better serve Yemekar. Without moving from Kal'Azgoth. It is said, he stole a score of enchanted items from Farrens forge before he left. They may be found scattered around the deep roads or the events. [Just some armour ideas]. His hair colour is dark red. ))
Droer Starbreaker (Son of Berren, from one of his illustrious visits to the Tavern.)
Nirin Starbreaker ( Son of Berren, the twin brother of Droer. They most likely fell together, as they gew up together and were inseparable)
Thir Starbreaker ( One of Wang Starbreakers eldest Children. Unlike his sister who eloped with a mountain dwarf, Thir did not disappoint his father. Developing to become a "true" Cave Dwarf. Ultimately becoming very Snobbish and arrogant. Leading for him to underestimate the threat of Ondnarch. Which as you can see lead to his death in this event)
Relvak Starbreaker ( Farrens oldest child, currently most favoured child. It was he and his twin brother Farren invested most of his time into. Relvak was most gifted out of the twins, having a natuaral affinity to Smithing, rarely seen since the time of Gotrek. Investing his time in teaching Relvak and his Twin Balvak most of his secrets. Naturally, Farren was angered when the twins volunteered to server as Smiths, to supply the garrison defending against Ondnarch with weapons and armours. But it seems they payed the ultimate price for their bravery. You can add some enchanted or unique items as a result of these characters. Since Farren taught these twins runesmithing + golemancy before they died. Although they might not have written anything down, he would have most likely made an enchanted item at least. And possibly a golem. So this may be an idea for a future event.))
Balvak Starbreaker (( Whilst his older brother was a gifted Smith, Balvak followed an odd path for a Starbreaker. The path of a warrior. Although he earned the scorn and disapproval of his Father, this dwarf was a gifted combatant. Inheriting the warrior blood from Gotrek, rarely seen in the Starbreaker line. Whilst his brother forged the weapons it was he who forged wielded the weapons. It is thought that in the early parts of the fight with Ondnarch. Paying the ultimate price along with his brother.))
Dronar Starbreaker (( Son of Thir Starbreaker, like his Father he inherited his arrogant traits. Treating his cousins with scorn as he believed that his bloodline should have inherited the title of Clan Father. It is most likely he fell in the initial attack, as although he was arrogant he was mostly useless. Mainly boastful, without anything to back his claims up. ))
Yuanna Starbreaker (( Wangs pride and joy, unlike her sister she did not elope with a mountain dwarf. Butt instead married another cave dwarf to keep the bloodline "Pure". Unlike her older sibling, she did not develop a sense of self importance or arrogant. Rather more humble and understanding, due to her close ties with her sister who eloped. She volunteered to join the garrison after the death of her husband. Seeking a place to die.))
Orina Starbreaker ((The Eldest daughter of Yuanna, with many of her kinsmen joining the garrison she chose to take part. Seeing it more as a clan matter than that of the Kingdom. Orina it seemed, developed to be arrogant and headstrong. Similar in some ways to the Paragon Yudora. It is said she always carried an amulet honouring the Paragon around her neck.[Possible event item] ))
Yuril Starbreaker ((The Youngest of Yuanna's three daughters. Like many of her kinsmen she signed up to join the garrison, but rather than inheriting the dutifall spirit of her mother. Yuril took after her aunt more, seeking to elop with a certain Mountain Dwarf present in the garrison. Unfortunately during a raid, her and her lover where ripped to pieces by Ondnarch minions. It is said she carried a token of Annabella on her at all times for good fortune. ))
There may be more, feel free to ask me if you wanna add more. To be fair there may be errors, I'll rectify them at a later date. I might add more if I feel like it. But I think that's enough for now, it easily explains the clans lack of numbers as well increasing the death count.
I think due to the religious nature of these Dwarves we could add some amulet items. Or some just random items, for added rp events. For example "Token of Annabella" , Journals, armour, weaponry, or even some random items with insignia's of certain clans, ect.
EDIT: Colour hair would be as stated on the clan page.
